Outcome measures
Primary outcome
Degree of leg extension, duration of treatment, Healing Index (months/cm) and
postoperative complications, Lower Extremity Functional Scale, range of motion
of hip, knee and ankle of the affected limb.
Varus valgus measurement after X-ray of the entire affected lower extremity.
Secondary outcome
N.A.
Background summary
Complications following fractures of the femur and tibia include segmental bone
loss and leg length discrepancy. Fracture consolidation may result in limb
shortening due to malunion, collapse of comminuted fractures or premature
closure of the diaphyse in children. A segmental bone defect is usually a
result of high energy trauma or debridement for osteomyelitis. These
complications may have severe negative impact on patient*s live and present
complex treatment challenges.
Ilizarov was one of the first who treated these patients with a modular-ring
fixator and transosseous wires to stabilize the bone fragments. He used this
method to generate new bone between the osseous surfaces that were gradually
pulled apart. This technique is called distraction osteogenesis.
Study objective
The purpose of this study was:
1) to assess the postoperative complications and fracture healing in patients
after posttraumatic distraction osteogenesis.
2) to assess the degree of the degree of function of the lower extremity upon
distraction osteogenesis.
Study design
A retrospective analysis of the patient*s notes was performed to determine the
duration of treatment and healing index. The healing index is defined by the
total duration of treatment divided by the number of centimetres of new bone
formation (months/cm). Furthermore, complications such as pin-track infections
and secondary operations were recorded.
All patients are invited for a personal physical examination to asses their
long term functional outcome. The functional outcome is based on the Lower
Extremity Functional Scale (LEFS) and the range of motion (ROM) of the hip,
knee and ankle joints. The LEFS is a 20-item self-report measure of physical
function. Each item is rated on a five point scale (0-4), with lower scores
representing greater difficulty. Total scores can range from 0 to 80. The ROM*s
were measured and listed according the American Medical Association guides to
the evaluation of permanent impairment.
In addtion, an X-ray of the operated lower limb (from hip to ankle) will be
made.
